Solution Overview
Problem
Conventional flash drives lack a grounding terminal, making them susceptible to static discharge and electromagnetic noise interference when connected to electronic devices.
Innovation Solution
A connecting part for storage devices that includes a grounding member extending across connecting interfaces, allowing for electrical connection to a grounding interface of an external device, thereby achieving a grounding effect and preventing static discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a grounding terminal is not adopted by the flash drive, then the device structure remains simple and compact, but static discharge and electromagnetic noise interference cannot be prevented
Solution Approach 1:
The grounding member is integrated with the connecting terminals to form a unified connector structure. The grounding member extends from one end of the body to the other end, merging the grounding function with the existing connector body rather than adding a separate grounding component. This integration achieves grounding protection while minimizing structural complexity.
Solution Approach 2:
The grounding member serves multiple functions: it provides grounding protection against static discharge and electromagnetic noise, while also serving as part of the connector's structural framework. The extending grounding member can contact grounding interfaces in various connector types (USB, IEEE 1394, etc.), making the solution universally applicable across different connector standards.
2Reliability
If a grounding member is added to the connecting part, then grounding protection is achieved, but the connector structure becomes more complex
Solution Approach 1:
The grounding member is merged with the connecting terminals within the same body structure. Rather than being a separate component, the grounding member is assembled to the body and extends through it, combining the grounding function with the existing connector framework. This reduces the number of discrete parts while achieving reliable grounding protection.
Solution Approach 2:
The grounding member is designed as a distinct element that can be separately assembled to the body, allowing for modular manufacturing and assembly. The grounding member extends from one end of the body to the other end, creating clear segmentation between the grounding function and the signal transmission terminals, while maintaining structural integration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents static discharge and electromagnetic noise interference by ensuring both the storage device and external device are grounded when connected, enhancing data transmission safety.
Implementation Method 1
The grounding member is assembled to the body. At least a part of the grounding member extends from one of the first and the second ends to another one of the first and the second ends. The connecting part of the storage device is grounded by contacting the grounding member to a connector of an external device
